2.2.2 AC Source Grounding
Ensure the power supply is connected to an appropriately rated AC outlet with the
recommended AC input connector as set out in Section 2.5.1 AC Input Power Connection.
There is a shock hazard if the power supply chassis and cover are not connected to an
electrical ground via the safety ground in the AC input connector. The third wire in a single
phase AC input connector and the fourth wire in a three phase AC input connector must be
connected to an electrical ground at the power outlet. Any disconnection of this ground will
cause a potential shock hazard to operating personnel.
This power supply is equipped with an AC line filter to reduce electromagnetic interference and
must be connected to a properly grounded receptacle, or a shock hazard will exist.
Operating the supply at line voltages or frequencies in excess of those specified may cause
leakage currents in excess of 5.0 mA peak from the AC line to the chassis ground.
2.2.3 Operating and Servicing Precautions
Exceeding the maximum model-rated input voltage may cause permanent damage to the unit.
Always disconnect power, discharge circuits, and remove external voltage sources before
making internal adjustments or replacing components. When performing internal adjustments
or servicing the power supply, ensure another person with first aid and resuscitation certification
is present. Repairs must be made by experienced technical personnel only.
Be sure to isolate the power supply from the input line with an isolation transformer when using
grounded test equipment, such as an oscilloscope, in the power circuit.
The power supply must not be operated where flammable gases or fumes exist.
2.2.4 Parts and Modifications
Do not use substitute parts or make unauthorized modifications to the power supply to ensure
that its safety features are not degraded. Contact the manufacturer for service and repair help.
